Abstract

Mobile telephone systems are widely used in the transport of valuables. Such systems are a suitable means of providing protection, but are vulnerable. The signals from mobile terminals can be criminally interfered with/jammed, thereby depriving the terminals' possessors of protection. The present invention remedies this by, irrespective of whether of not there is any voice or data transmission, having each mobile terminal transmit signals regularly, randomly or when triggered by an event. The regularly or randomly transmitted signals are registered in the system's switching center. Where a signal is missing, information on the absence is, after logic analysis in the switching center, immediately and automatically transmitted to the alarm reception center. In the present invention, it is an extra advantage to have mobile telephone position monitored by satellite and to have satellite data directly added to the signals from the mobile terminals. In the event of signal failure, alarm reception can then immediately geographically pinpoint mobile terminals or their positions immediately before the break.
